People mover project (control system part)
(BRAC University, 2011-12-07)
People-Mover is an electrical self-motivated medium. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes applied to ...
Performance analysis of dye sensitized solar cell based on ZnO compact layer and TiO2 photoanode
(BRAC University, 2018-08)
Harnessing solar energy as an alternative solution to power production. Power can
be produced through burning fossil fuels. To gain optimum benefit through solar
energy is an extreme challenge for scientists and researchers ...
Alternative solar hot water system with multistorage tank
(BRAC University, 2010-08)
The use of renewable energy has been spread all over the globe very rapidly. Renewable energy is the energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable ...
Solar electric ambulance van unfolding medical emergencies of rural Bangladesh
(© 2016 IEEE, 2016-10)
Rickshaws are a key mode of transportation in Bangladesh. When it was changed to electrically-assisted ones, it achieved prevalence but was soon banned because of overconsumption of power from the national grid. In ...

Design and comparative analysis of single-layer Graphene Microstrip patch antennas operating at Terahertz frequencies
(Brac University, 2019-04)
The solution to the growing demand of higher speed wireless communication is the terahertz (THz) band, which will reduce the shortage of spectrum and capacity limitations of current wireless systems and will open new fields ...
Design and implementation of solar heater system
(BRAC University, 2016)
Overly populated and developing countries, such as our country Bangladesh is facing energy resources scarcity over the last few decades. Specially, the rural areas in Bangladesh which covers at least 50 % of our land suffers ...
Band structure study of graphene and transition metal dichalcogenides heterostructures
(BRAC University, 2017)
According to Moore’s Law, it is predicted that the number of transistors –the building
blocks of any modern electronic device– on integrated circuits per square inch
will double every year. However studies show that the ...
Air pollution monitoring system using unmanned aerial vehicle in Bangladesh
(Brac University, 2019-12)
Over the last few decades, the main minacious and dodgy calamity that grab the world’s attention is “Greenhouse Effect”. It is evident that Carbon dioxide, methane, nitrous oxide, fluorinated gasses and water vapor are the ...
Development of a prototype voice communication system
(BRAC University, 2012)
A cellular voice communication system is developed using two transceiver (handsets).The RF components of the handsets were collected and integrated with proper care. Our focus was on integrating RF transceivers operating ...
